Explanation:
Polymerization is a chemical reaction in which small units called as monomers combine together to result into bigger molecules called as polymers.
Addition polymers : Polymers in which small units called as monomers are joined end to end to form a bigger molecule. Example: polystyrene: formed by combination of styrene monomers
PVC: formed by combination of vinyl chloride monomers
polypropylene: formed by combination of propylene monomers
Condensation polymers: Polymers in which small units called as monomers are joined to form a bigger molecule and small by products are also formed along with the polymer. Example: Nylon-6 : formed by combination of adipic acid and hexamethylene diamine
